I think perspective can easily resolve this issue, but getting both sides to see the other side's point of view is what seems to be the problem here. A little bit of understanding could probably be given by the older users, but I think I share their sentiments with the phrase, "Give an inch and take a mile". A lot of the older users don't wake up in the morning and think to themselves, "Who's coffee should I shit in today?", but their tolerance for what seems to be the standard for what younger posters deem acceptable is understandably low. It wasn't something that happened overnight, we didn't all just gather at 4 Peaks one night in hooded robes decide to just turn the crotchety old man switch on and just piss all over your corn flakes. This current crop of new, young players certainly isn't the first and won't be the last group that this board has to deal with. The problem as I see it, is that a lot of the newer players don't seem to be learning the norms as it is practiced by the older AA community at large. Don't get me wrong, this isn't to say that there is an expectation that all new players will learn and integrate into the community (regardless of age), but it looks to me that we are getting lower and lower numbers of new players who seem to ingratiate themselves with the currently established AA community. The concern here is that the new generation is "doing it wrong" and that they will pass this on to other new players if no one speaks up about it. Granted, how an older generation AAer speaks up about it could be a little more diplomatic, but again experience has shown that diplomacy will be met with either apathy or outright hostility. It is an uphill battle for you new guys, because you also have to deal with all the bad experiences from the earlier groups of new people that have burned into the memories of the older guys. Initiative should be taken on both sides to engage in more civil discourse, but as it stands, you new guys definitely do have to step up, it is not fair that you are being lumped in with past groups of new guys, but that is just the way it is. Don't act like you're rocking an extra chromosome all the time and things will get better.
On a side note about the "Grammar Nazi" remarks, it is true that it can be seen as a sign of OCD when someone nitpicks a post for even minor grammatical infraction, but the perception here is that if you don't take the time to review your post before you hit the post button, then you probably didn't put much thought into your post to begin with. Why should we read something that only took you the time it takes to type it up on your smartphone and post it? I wasn't timing how long it took me to make this post, but I've read it over several times before hitting post. This all goes back to xaviermace's comment about not treating this message board as a real time chat room, you are not under the gun whenever you post here, so stop treating it like that.
